Yeah you know saffron is a natural thermometer when temperature is above 18 it blooms and below it remains close and this fall I bought plenty of bulbs they are very expensive one bulb cost me around half dollar but only a single plant bloom but I will save this bulbs for next year and I hope they will do well next time if you don't know what bulb is it is something like onions or other swollen roots .

Interesting. I hope it goes well ;)
